Abstract
A polymer is represented by Formula (I): wherein X is a substituted or unsubstituted C2-C5 alkylene, alkenylene, or alkynylene group; Y is a substituted or unsubstituted divalent C2-C5 aliphatic hydrocarbyl group; Z is a divalent binding group; k is in a range from 0 to 3; m is in a range from 7 to 100; p is in a range from 0 to 30; n is in a range from 0 to 3; and q is in a range from 3 to 50. The polymer is used as a nucleating agent for PET resin.
